Engineered from the ground up to be the mostcomfortable hunting bow we've ever made, we started with our amazing new EVOLVE® Cam System (ECS),which gives this hunting bow an unbelievable 90% let-off and the smoothest shot on the market.But PSE wasn't done yet...we paired the ECS with our all-new ultra stiff forged riser design for amazing rigidityand shot stability, our Wide-Track Limb System and Wedge Lock™ Speed Pocket for deadeye accuracy and 346fps of shooting power, and topped it all off with our new RollerGlide® cable guard system to eliminate friction.We also added built-in riser stabilization ports to deliver a bow that is pure shooting nirvana!
